Obesity‐associated lymphedematous mucinosis: dermoscopic‐histopathological findings and differential diagnosis

Juvenile Psammomatoid Ossifying Fibromais a rare fibro-osseous tumor seen in children and adolescentand mostly arising from the cranio-facial bone.We report a case of 18-year-old boy who presented with diplopiaand progressive right fronto-orbital swelling. On plain radiograph and CT, it was diagnosed as fibrous dysplasiaand mucocele as differential diagnosis. The tumor was resected and histopathological examination showed psammomatoid features. Therefore, the diagnosis of Juvenile Psammomatoid Ossifying Fibroma must be based on both radiological and histopathological findings.

Sarcoidosis is a chameleon disease of unknown etiology, characterized by the growth of non-necrotizing and non-caseating granulomas and manifesting with clinical pictures that vary on the basis of the organs that are mainly affected. Lungs and intrathoracic lymph nodes are the sites that are most often involved, but virtually no organ is spared from this disease. Histopathology is distinctive but not pathognomonic, since the findings can be found also in other granulomatous disorders. The knowledge of these findings is important because it could be helpful to differentiate sarcoidosis from the other granulomatous-related diseases. This review aims at illustrating the main clinical and histopathological findings that could help clinicians in their routine clinical practice.

Radiological Features

Isolated tuberculous epididymo-orchitis is rare and may present with clinical and radiological features similar to those of testicular tumor. It is thus a diagnostic and therapeutic challenge. A 40 yrs old male presented with left sided mass in scrotum for past 6 months, which was clinically and radiologically diagnosed as testicular tumor with hydrocele. FNAC was attempted twice but was inconclusive. Left sided orchiectomy was done. However, the histopathological findings of testicular mass revealed features consistent with tuberculous epididymo- orchitis (TEO). This case emphasizes that patient may present with isolated TEO, which is considered an unusual presentation of tuberculosis and can masquerade as testicular tumor clinically and radiologically. But in countries where prevalence of tuberculosis is high, tuberculous orchitis must be considered in the differential diagnosis of testicular swellings.

Porphyria cutanea tarda (PCT) is the most common type of porphyria worldwide and is often initially diagnosed when cutaneous manifestations arise. We present two patients where misdiagnosis of PCT occurred due to the condition masquerading as epidermolysis bullosa acquisita histologically. In patients with undifferentiated bullous/erosive skin conditions occurring in photo-distributed regions, PCT should be considered in the differential diagnosis irrespective of histopathological findings on biopsies and further investigated and treated appropriately.

A 52-years-old female presented with a history of a painless, progressive swelling in the left lower eyelid of one-year duration. The lesion was excised twice as a chalazion and recurred. Excisional biopsy of the mass was performed and histopathological findings were consistent with those of trichilemmal cyst. We report a rare case of trichilemmal cyst of the eyelid which was masquerading as chalazion for which the patient had undergone multiple surgeries. Wide excision was done and diagnosis was confirmed on histopathology. There was no recurrence seen till 2 months of postoperative period. Trichilemmal cyst, although rare, should be considered as differential diagnosis of recurrent chalazion.

Cytological Features

SMARCA4-deficient thoracic sarcoma (SMARCA4-DTS) is a recently described entity of thoracic sarcomas with an undifferentiated rhabdoid morphology and SMARCA4 inactivation. Regardless of some reports about the histopathological findings so far, there have been only a few reports about the cytological features. In this article, we present the pathological features of 2 SMARCA4-DTS cases, including the cytological findings. Histopathologically, the tumor cells showed atypical loosely cohesive large epithelioid cells focally with geographic necrosis. Some cells were characterized by rhabdoid cells. Both patients showed intrathoracic masses with a history of smoking, and loss of SMARCA4 expression was confirmed with histopathological specimens. Immunohistochemically, tumor cells of both cases were at least focally positive for cytokeratin, CD34, CD99, synaptophysin, SOX2, and SALL4. In addition, tumor cells demonstrated significantly reduced expression of BRG1/SMARCA4 and SMARCA2. In conclusion, SMARCA4-DTS should be taken into consideration in the differential diagnosis of tumors with undifferentiated rhabdoid morphology involving the thoracic region.

Severe pain in the finger caused by an abnormal Pacinian corpuscle is a rare condition. We have recently encountered three patients diagnosed with a heterotopic Pacinian corpuscle, based on histopathological findings. When making a differential diagnosis of unexplained severe pain in the finger, abnormal Pacinian corpuscles must be taken into account in addition to glomus tumour and other types of painful soft-tissue tumour.

Myopericytoma is a rare benign tumour composed of pericytic cells that show myoid differentiation and have a tendency for concentric perivascular growth. It belongs to a spectrum of perivascular myoid cell neoplasms. To date, only a small number of cases of myopericytoma involving the oral cavity have been reported. We describe a case of myopericytoma presenting as a slowly growing tongue nodule in a 61-year-old woman. A diagnosis of myopericytoma was established with the histopathological findings combined with immunohistochemical staining. Myopericytoma should be included in the differential diagnosis of well-circumscribed, slow-growing lesions of the oral cavity.
